Skype - Free VoIP Software

Skype is a free application that allows you to try VOIP with a minimum of hassle. It works like this: You download and install the app, a friend of yours installs the app. You both have voice chat across the internet for free. It is that simple. There are only a few hardware requirements, which most PC systems should meet out of the box:

PC running Windows 2000 or XP (pro or home version)

400 MHz processor or faster

128 mb Memory minimum

10 MB free disk space on your hard drive

Sound Card, speaker(s) and microphone

Internet Connection - minimum 33.6k connection speed

Skype is ad free, allows you to make unlimited calls worldwide, lets you talk to up to 5 people at once, works with firewalls, and encrypts your calls.

Skype is spyware and adware free, so you shouldn't have any unwanted nasties after installation.
